A (lomey fiatented Jan. 12, 1932 EJNEPEE) a is FILLING IMPLEMENT Application filed March 27, 1930. Serial Iii-4 9,41

This invention relates to new and useful.

improvements in crevice filling implements and moreparticularly to devices of thischanacter which are especially adapted to depos1ting bituminous material in crevices or joints.

of concrete roads, pavements or floors. I

An important object of the invention is to provide, in a manner as hereinafter set forth, a crevice filling implement of theaforemen- 1, tioned character whichiis 1nanually' operated and embodying a novel construction and arrangement of parts to render the sameportable and easily carried from place to place in the hands of the operator. 7

Another important object ofthe invention is to provide a crevice filling implement of the character set forth above which embodies novel guide means at the discharge end of the implement for maintaining said discharge end in position over the crevice or joint to be filled when the device is in operation. v v

A further object of the invention is to provide a crevice filling implement embodying a novel construction of discharge nozzle hav: ing a spring controlled manually operable control valve associated therewith whereby the implement will require the use of only one hand of the operator to manipulate and carry the same when in use. i H

Still further objects of the invention are to provide a crevice filling implement of the character set forth which will be simple in construction, strong, durable, 'efiicient. in its use and which may be manufactured at low cost.

All of the foregoing and'still further obj ects and advantages of the invention maybecome apparent fro-m a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein: r i t Figure 1 is a vertical sectional view-ofa crevice filling implement constructed inraccordance with this invention;

Figure 2 is a view in top plan thereof, with a portion of thehandle broken away to illustrate the valve operating handle.

Figure '3 is a fragmentary view in side elevation showing thedischarge end portion of the implement withthe guide rod mounted in positiononsthe discharge nozzle. j

; Referringto the drawings in detail, it will be seen thatfthe reference numeral l--d esigmas aftaperedhopper', or container which is formed of-rany; suitable material, preferably: metal, and which is opened at its top andhas its upper end rolled in a manner to provide the-bead 2." The lower or restricted end of the hopper 2 terminates in an integral inturned flange 3 which provides a circular'opening in the lower end of the hop:

per 1 through which is inserted an externally threaded pipe section 4 which is of uniform diameter throughout.

lii collar 5 is threaded on the inner end of the pipe section 4 for rest on the-innerside of the flange 3 and a lock nut 6 is threaded on the outer xportion of said pipe section. A gasket 7 is'mountedonthe pipe section 4 betweenthe lock nu't6 and theflange 3 and, as best illustrated in Figure 1 of the drawings, said lock nut and the flange 3 are adapted to co-act ina manner to securely clamp the pipe section 4 in position A tapered discharge nozzle '8 is provided with an internally threaded flanged end por tion 9 for threaded engagement on the lower end portion of the pipe section 4 and is further provided with a bore 10 extending longitudinally; therethrough and merging into a counterbored portion providinga valve seat 11, communicating with the bore of the pipe section at. A valve'head 12 is mounted on the lower end of the elongated stem 13 for frecipr-ocatory movement through the pipe section 4 in a manner to seat in the counterbore "11 to open or close the passage 10 of the nozzle 8. The upper portion of the stem" 13 extends slidably through a transversely disposed bracket 14: having downturned legs 15 which abut diametrically opposite side of the upper end portion of the hopper '1 on the "interior thereof and are secured theretothrough the medium of the bolts 16. Above the bracket '14 the stem 13 terminates in ahandle forming loop 17 which is disposed within a substantially'inverted U-shaped carrying handle 18 secured to the transversely extending portion of the bracket 14: through the medium of the'foot portion 19 and the bolts 20.

A washer 21 is mounted on the stem 13 in spaced relation to the upper end thereof and a coiled spring 22 encircles said valve stem and has one end impinged against the bracket 14% and its opposite end impinged on said washer 21 in a manner to yieldingly urge the valve 12 into position on the seat 11 to close the passage 10. i

The lower end portion of the discharge nozzle 8 has formed integrally thereon a stop flange 23 provided with an opening through which slidably extends aguide rod 24 which terminates, at its upper end, in an integral substantially right angularly disposed loop 25 which slidably' encircles the discharge nozzle 8 and maintains the rod 24 in longitudinal alignment therewith in a manner to permit sliding movement of said guide rod on said nozzle and through the stop flange 23. The loop 25 and stop flange 23 engage with each other in a manner to prevent separation of the guide rod from the nozzle; As Will be apparent from a study of Figure 3 of the drawings, the loop 25 is provided with a free end and this specific arrangement permits saidloop to be expanded or contracted due to its inherent resiliency in a manner to frictionally grip the tapered discharge nozzle 8 for maintaining the guide rod 24 in the desired position thereon against longitudinal J movement.

In use, the hopper 1 is filled with th bituminous material and the guide rod' 24 is inserted in the crevice or joint to be filled. The hopper is then moved in the general direction followed by the crevice or joint in a manner to-drag the guide rod 24 therethrough and the nozzle 8 is thus maintained in position above said crevice or oint. The hopper 1 is carried through the medium of the handle 18 and the operator grasps the valve handle 17 in a manner to disengage the valve head 12 from the seat 11 and permit the discharge of the bituminous material through the nozzle 8 into the crevice or joint. In Figure 1 of the drawings the reference numeral 26 indicates a portion of a concrete road, pavement or floor and '27 indicates the crevice or joint to be filled. When the operator releases the handle 17 the coil spring 22 automatically engages the valve head 12 on the seat 11 to stop the discharge of the bituminous material from the hopper, as will be understood. As before stated, the inherent resiliency of the loop 25 permits longitudinal adjustment of the guide rod '24 on the tapered discharge nozzle 8 and said guide red will befrictionally maintained. in adjusted position.

It is believed that the many advantages of a crevice filling implement constructed in acter described comprising a tapered hopper having an open top, a tapered discharge nozzle detachably mounted'in the bottom of the hopper and communicating therewith, said nozzle having a valve seat formed therein, a manually operable spring controlled valve mounted in the hopper and engageable with the'seat to discharge the passage of material through the nozzle, an integral stop flange on the free end portions of the nozzle having an opening therethrough, a guide rod disposed against one side of the discharge nozzle and extending for longitudinal sliding adjustment through the opening in the stop flange and projecting longitudinally from the free end of the nozzle for insertion in the crevice to be filled in a manner to maintain said nozzle in position thereover, and an flange formed on the lower end of the hopper providing an opening communicating with the interior thereof, an externally threaded plpe section of uniform diameter throughout extending through the opening into the lower end portion of the hopper, a collar threaded on the inner end portion of the pipe section and engaged on the inner side of the flange, a lock nut threaded on the outer portion of the pipe section and, in conjunction with the collar, constituting means for detachably securing the pipe section in position, a gasket mounted on the pipe section between the lock nut and the flange, a tapered discharge nozzle threadedly engaged on the outer end portion of the pipe section and communicating therewith, a central valve seat formed in' the discharge nozzle, a manually operable spring controlled valve mounted in the hopper and engageable on the seat in a manner to control the passage of material through the nozzle and a guide rod mounted for longitudinal sliding adjustment on one side of thedischarge nozzle and projecting longitudinally from the free end thereof.

3. A crevice filling implement of the char-V acter described comprising a hopper, a tapered discharge nozzle mounted on one end of the hopper, an integral stop flange on the free end portion of the nozzle having an opening therethrough, a guide rod disposed against one side of the nozzle and extending for longitudinal sliding adjustment through the opening and an integral resilient loop formed on one end of the guide rod'encircling the nozzle and frictionally engaged therewith in a manner to securethe guide rod in adjusted position thereon.

In testimony whereof I aflix my signature.
